Rompler
An instrument that plays factory samples out of ROM but can't record its own — a sampler with the record button surgically removed.
The word is a portmanteau of ROM and sampler, coined in the early 1990s with a certain sniffiness by people who felt a real synth should build its sound from oscillators. The Korg M1 of 1988 proved the business case: short samples of piano, strings and drums in memory, some filtering and effects on top, and a workstation that outsold nearly every synth before it. The E-mu Proteus in 1989 and the Roland JV-1080 in 1994 made the format a fixture of studio racks.
Cheap memory meant the patches sounded like the real instruments without the player having to understand anything about synthesis. General MIDI modules and sound cards loading SoundFonts are the same idea sold to consumers. The complaint that they all sound alike is partly fair: thousands of 90s tracks share one piano preset.
